John Holland CPB Contractors Ghella Joint Venture (JCG) was awarded the $1.63 b contract to design and build the tunnels for the Sydney Metro West – Eastern Tunnelling Package (ETP).
The ETP works include construction of 3.5-kilometre tunnels under Sydney Harbour between The Bays and Sydney CBD, and the excavation of Pyrmont and Hunter Street stations.
Starting at The Bays, tunnel boring machines crossed under the harbour near the Anzac Bridge, before heading to the new Pyrmont Station and then under Darling Harbour before reaching Hunter Street Station in the heart of the CBD.
